I usually do this with a single graphics card. So my suggestion might
not be useful to you. But...

I would start with lxrandr. Because even me being a staunch CLI
advocate it is sometimes easier to click the mouse. This is simply an
graphical interface to xrandr.
# apt-get install lxrandr
$ lxrandr
It also installs a menu for it under Applications/System/Monitoring
as LXRandR too so you can menu pick it instead of typing it. Then see
if it allows you to turn on and set up both monitors.
Then for batch mode automated startup I have the following in my X11
startup file.
if xrandr --query | grep -q HDMI2; then
xrandr --auto --output HDMI2 --right-of HDMI1
fi
Initially both of my monitors have the same display. Setting the
above command sets my second monitor to the right of my first monitor
and then they display one unified display.
Again, I am using a single graphics card with dual outputs. YMMV.
